I also got the formula for oxygen turning into ozone wrong, so I think I will get around 84 out of 90... which will do.

I had my chemistry today, and there was a 1 mark question that asked for the empirical formula of poly(e)thene. I wasn't sure, but I thought that the empirical formula was the basic, canceled down formula - so wouldn't the formula for polythene be the same as the formula for ethene C2H4, as polythene is a chain of 'n' ethene molecules?
I can't seem to find the answer on the internet. Perhaps someone could enlighten me?
Thanks
P.S This is my 100th post :D:D:D
